Access to Raspberry from Win11: host unreachable

Installation Home Assistant OS
1

Hi,

I installed HA on my Raspberry. Everything is running so far, the installed app on my iPhone runs and the web UI using chrome on my iPhone runs as well.
But: Trying to reach the server using the IP:8123 (doing the same on my iPhone Browser successfully) runs into a “timed out”. A ping to the IP reacts with “destination host unreachable”.
I have a second Pi in the network, also with static ID, with is reachable using ping from the PC
Windows 11 is running on the PC.

Any ideas??

regards Heiner

Are you using http: or https: ?

Unless you have encryption setup it should be http.

You mentioned you could reach your HA Pi via your iPhone browser - is the HA Pi using a wireless connection or wired connection?

Is your PC is using a wired connection?

Hi all,

thanks for your ideas.
the connection is back again, everything is running now for mystical reasons. Without restart, without anything. Just about one hour later the next attempt worked.
Seems like a kind of caching reset or something.
Facts:
PC and PI are connected via WiFi
IP address of PI changed to static a few days ago.
